Keep your costs down. In order to turn a profit on what you're selling, choose to sell an item that's inexpensive to make. Lemonade is a classic because all of its ingredients (water, sugar, lemons or lemon juice concentrate, and ice) are fairly cheap and easy to obtain. Popsicles are another favorite because they can be bought in large quantities from the store!
If you spend a lot at Amazon.com, for example, you can get a card that rewards you with 5% cash back on Amazon purchases -- which can really add up. Stores such as Target, Costco, Gap, Lowe's, TJX, and Wal-Mart also offer cards. Plenty of retailer cards offer 3% to 5% in cash back or discounted prices and many offer other perks, too, such as free shipping. If you travel a lot, travel-related credit cards can help you rack up lots of points and rewards that can be used instead of cash, keeping more cash in your pocket.

You’re already broke, and your car just conked out. Or maybe you’re cash-strapped until next week’s payday, but you’re short on rent, can’t make the minimum payment due on your credit card bill, or simply forgot you need to chip in for a birthday gift. When you’ve run out of money, there’s an endless number of reasons why you might need cash – quick.
Sell scavenged valuables. If you have a metal detector, or even just a good eye, go to public places where people are likely to drop something unnoticed (such as parks, beaches, and shopping areas), and look for money, jewelry and other valuable goods. This method isn’t very reliable, but you just might get lucky and be able to find something you can sell quickly for cash.
